To all ebhom it'm 'ag concern:

Be it kno'wn-that I; JOHN H. HAMLIN, a citizen ofthe United States, and resident of the city of New York; borough "of Manhattan,- county} and "State of; New York, have invented a new-and" Improved Fruit and Vegetable-Peeling Machine, of which the-following is a full, clear, and exact description; v This inventi'on relates tovegetable peelers and has particular reference to -1neans fo'rpeeling potatoes or similar vegetables by an abrasive action.

Among the objects of this invention is to provide a machine adapted-for rapid operation and so designed 'as to treat large quantities of'pota-toesin a thorough manner and yetwiththe minimum amount of waste of the vegetables. I

Another object of'the invention isto provide a'machirie adapted forthe manipula tion of thepotatoes ina body' of water the potatoes and water being retained together as a single mass during the treatmentof the potatoes whereby the operation-is facilitated, the entire" mass "being delivered from the machinefor theseparation of the potatoes from the parings and water;

vYVithftheJ foregoing and other objects in view the invention consists in thearrange nient and combination of parts hereinafter described and cla-ime d, and while the invention is not restricted tothe exact details of" construction disclosedor suggested herein, still for the purpose of illustrating a practical embodimentthereof reference is hadto the accompanying -drawings, in which like referencecharacters designate the same parts in the" several views, andin which' Figure l is aside elevation of a preferred embodiment of the invention. v

Referring now more particularly to the drawings I show a rigid frame of any suitable construction 'comprisingrright and left standards' lOandfll respectively each hav in'g a horizontalcrossbar I2 and any suitable cross braces-13 to make the same: rigid and sufficiently strong with a minimum amount of material.

At the central portions of'the: crossbars 12 are supported right and'lleft bearings 145 and '15- respectively, the axes of which are inhorizontal alinement; In the bearings is journaled a hollow shaft 16 one end of which *is closed where it projects through the bearing 15L while theother end'and intermediate portions thereof are open 'or tubular. The intermediate portion of the shaft is provided with a series of jet holes 16", the open end-of the shaft beingjournaled'in'the bearing 15 and provided with a packing g l'and- 1'7 screw threaded thereon to ake it watertight, l I

The main" portion of my improvement comprises a drum 18 shown as'substantially of cylindrical form supported upon the shaft 16 and coaxial therewith. This drum is made preferably of some suitable strong thin material such as sheet metal indicated at "-19 and is imperforate except where the shaft passes through and also where the closure is provided about the center of the 03 1- inder longitudinally of its axis. The interior of the drum is lined'in a peculiar manner as indicated at "20 with a composition having considerable; body and weight lined with a strip'of reinforcement material 21 and having surface 'composedof or impregnated with an abradant preferably of a materi'al now wellknown on the market as Hamlinite, of a sharp granular material. having someof the characteristics of a carborundum. Inaddi tion to the abrasive facing of the lining for the drum it is to be noted that the body of lining is so constructed as to provide convolutions or irregularities of "difierent sizes or Shapes against the inner them amovement at right angles tothat given by the rotation of the drum. Adjacent to the hub portions of the drum the lining member 20 is provided with the hub enlargements 20, surrounded with tubular portions 21 of the reinforcement material. The axial apertures for the shell of the drum are surrounded or closed by means of thinlbles 23 secured rigidly to the drum and fixed inany suitable manner upon the shaft. The outer or opposite ends of the thimbles abut faces of the bearings i l and 15, whereby the drum is held from endwise movement The closure 24:, above referred to, comprises a metal base 25 and a lining member 26 of a character somewhat similar to the lining body 20 and faced if desired with the abradant. This closure is hinged at 27 to one side of the hopper mouth 28 of the drum and is adapted to be locked closed by means of a hasp '29 at the side opposite the hinge. A flexible line 30 leads from the hasp over a pulley 31 at one side of the drum and the end of the line is provided with a ring 32 for manipulating it, said ring being adapted to cooperate with the keeper 83 carried by the drum, whereby when the closure is locked shut theholding means therefor will rotate in unison with the drum.

34: indicates a nozzle projecting axially into the open end of the shaft 16 through the packing gland 17 thereof. This nozzle isfprovided with a globe valve or its equivalent 35 to control the admission of water therethrough intothe shaft 16 and thence intothe drum. through the jets 16. The nozzle member is bent at substantially a right angle and held from rotation by means of a bracket 36 secured to one of the cross bars 12. Any suitable hose or tube 87 may be connected to the outer end of the nozzle memberto convey the water from any desired source. I

The frameis so designed as to accommodate a pan or receptacle 38 beneath it in which is fitted a reticulated tray 8 40 indicates a hook carried by one of the cross-bars 12 and adapted to cooperate with an eyelet 41 carried by the drum to hold the drum stationary in any desired position.

drum turned so as to neat its The operation of the machine may be briefly summarized as follows:.ln view of the foregoing specific description with the drum held with its upper mouth 28 elevated and the closure thrown open, a quantity of potatoes, for example, are introduced into the drum, the potatoes preferably just about one half filling the same though a smaller number may be treated with good advantage. The valve 35 is then opened to admit water into the drum to just about cover the potatoeswhen the valve will be closed again. The drum is then rotated at a moderate rate of speed by any suitable power or hand means applied to the end of the shaft 16 oppositethe nozzle; The means indicated comprises a combined hand wheel a2 and pulley e3 keyed or otherwise secured to'the end of the shaft. As a result of the rotation of the drum the mass of potatoes and water is caused to guide relatively along or over the abrasive lining surface of the drum and at the same time the potatoes are moved by the protuber ances toward the ends of the drum, and owing to these two movements and theundulations practically all surfaces of the p0? tatoes are presented to the abradant whereby the peel or skin thereof is all quickly and effectively removed, with a very slight loss of potato. At the expiration of a few minutes this operation will be completed, when the closure will be unlocked and with the bring the hopper mouth downward, as shown in Fig. 3, the entire mass of water, parings and peeled potatoes will be delivered-into the tray 39. When the tray is lifted from the receptacle 38 the water and parings willremain in the receptacle while. the peeled potatoes will be carried in the tray. One immediate ad vantage accruing from the use of a constant mixture of water, vegetable and par= ings, consists in the fact that the sharp, granular, abrasive surface of, the drum never becomes clogged or foul. Y

While 1 refer herein. more or less specifically to the use of the machine as a potato peeler, I wish itto be understood thatit is adapted for paring other, vegetables as well as certain kinds of fruits, especially fruits designed for canning, which are still ina firm or partially ripened condition;
